Why does NF3 have a smaller bond angle than NH3?
2016年12月29日 · I've already read many answers about the reason why $\ce{NF3}$ has a smaller bond angle than $\ce{NH3}$ , but I can't seem to understand them. Here's my understanding of the situation: $\ce{NH3}$: Here N is more electronegative than H so a large electron cloud is crowded over N. This will push the bond pairs $\ce{N-H}$ away from the …
Why bond angle of NH_3 is greater bond angle of PH_3? - Toppr
Nitrogen is more electro-negative than phosphorous and hence attracts electron more towards itself from bond pair with hydrogen, as compared to attraction of electrons by phosphorous in P H 3. The electrons in N H 3 come closer to nitrogen and …
Arrange NH_3, PH_3, AsH_3, SbH_3 in increasing bond angle.NH_3 …
As we move down the group, radius of elements increases and electronegativity decreases so bond angle decreases. so bond order is N H 3 > P H 3 > A s H 3 > S b H 3 107 93 92 91
Bond angles for the hydrides - Chemistry Stack Exchange
2015年7月10日 · $\ce{NH3}$ has one lone pair: the bond angles are contracted a little because of the grater repulsion of the lone pair to $107.8^\circ$. $\ce{H2O}$ has two lone pairs: the bond angle is contracted further due to the repulsion of two lone pairs to $104.5^\circ$.

Bond angles in NH3 and NCl3 - Chemistry Stack Exchange
2018年3月15日 · The bond angle in a molecule is inversely proportional to the electronegativity of the surrounding atom if the central atom is same. This also happens with $\ce{NH3}$ and $\ce{NF3}$, as bond angle in $\ce{NH3 > NF3}$. Why then is the bond angle in …
Why the bond angle of PH3 is lesser that that of PF3?
We can explain why the bond angle of $\ce{NF3}$ (102°29') is lesser than $\ce{NH3}$ (107°48') by the VSEPR theory, since lone pair lone pair repulsion is greater than lone pair bond pair repulsion. Then for $\ce{PH3}$ and $\ce{PF3}$, also, it is expected that the bond angle of $\ce{PF3}$ will be smaller. But I found that the thing is just ...
Bond angles in NH_3 and H_2O are :109^circ and …
So, the bond angle in N H 3 is less than 109.5 ∘ which i s about 107 ∘. As water has two lone pairs the bond angle is further reduced to 104.5 ∘ Bond angles in N H 3 and H 2 O are 107 ∘ and 104.5 ∘

Why is the bond angle H-P-H smaller than H-N-H?
2014年7月3日 · The $\ce{H-N-H}$ bond angle in ammonia is around 107 degrees. Therefore, the nitrogen atom in ammonia is roughly $\ce{sp^3}$ hybridized and the 4 orbitals emanating from nitrogen (the orbitals used for the 3 bonds to hydrogen and for the lone pair of electrons to reside in) point generally towards the corners of a tetrahedron.
